C# Update Table using SqlCommand.Parameters

Question

I'm trying to update an MSSQL table using SqlCommand, I think it's a syntax error with my T-SQL, but here is what I have so far:

SqlCommand sqlCmd = new SqlCommand("UPDATE yak_tickets SET email = @emailParam, subject = @subjectParam, text = @textParam, statusid = @statusIDParam, ticketClass = @ticketClassParam WHERE id = @ticketIDParam", sqlConn);

The parameters are working as they should, however, the table never gets updated when I run the code. Any help would be appreciated =)

Here is the rest of the code:

    #region Parameters
    /* Parameters */
    sqlCmd.Parameters.Add("@ticketIDParam", SqlDbType.BigInt);
    sqlCmd.Parameters["@ticketIDParam"].Value = ticketID;

    sqlCmd.Parameters.Add("@emailParam", SqlDbType.NVarChar);
    sqlCmd.Parameters["@emailParam"].Value = ticketToBeSubmitted.getEmail();

    sqlCmd.Parameters.Add("@subjectParam", SqlDbType.NVarChar);
    sqlCmd.Parameters["@subjectParam"].Value = ticketToBeSubmitted.getSubject();

    sqlCmd.Parameters.Add("@textParam", SqlDbType.Text);
    sqlCmd.Parameters["@textParam"].Value = ticketToBeSubmitted.getTicketContent();

    sqlCmd.Parameters.Add("@statusIDParam", SqlDbType.NVarChar);
    sqlCmd.Parameters["@statusIDParam"].Value = ticketToBeSubmitted.getStatus();

    sqlCmd.Parameters.Add("@ticketClassParam", SqlDbType.NVarChar);
    sqlCmd.Parameters["@ticketClassParam"].Value = ticketToBeSubmitted.getTicketClass();
    #endregion

    #region Try/Catch/Finally
    /* Try/Catch/Finally */

    try
    {
        sqlConn.Open();
        sqlCmd.ExecuteNonQuery();
    }
    catch (SqlException sqlEx)
    {
        sqlErrorLabel.Text = sqlEx.ToString();
        sqlErrorLabel.ForeColor = System.Drawing.Color.Red;
    }
    finally
    {
        sqlConn.Close();
    }

And the method's signature:

  public static void updateTicketInDatabase(Ticket ticketToBeSubmitted, Label sqlErrorLabel, int ticketID)

Answer 1

UPDATE FROM is invalid syntax (edit: OP corrected this). The problem might also be the "text" column. text is a keyword in SQL Server, since it's a datatype. Try putting brackets around it.

UPDATE yak_tickets 
SET email = @emailParam, 
    subject = @subjectParam, 
    [text] = @textParam, 
    statusid = @statusIDParam, 
    ticketClass = @ticketClassParam 
WHERE id = @ticketIDParam

Answer 2

Had to use if(!Page.IsPostBack)
